Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed June 6, 1918, Serial No. 238,418. Renewed July 12, 1919. Serial No. 810,456.

To all whom it may concern:

Be it known that I, WILLIAM KRAFVE, a

u citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useyield or accommodate itself to the twisting or straining of the chassis frame.

In its simplest form, the invention consists of a pair of trunnion-like suspending members, that extend from the opposite sides of the rear portion of the engine base or crank case, and a central suspending member at the forward portion thereof, which central point of suspension may be the forward extension of the engine crank shaft andwhich finds bearing in a spanner frame arranged transversely of and secured to the vehicle chassis.

In the drawings, which exemplify one form that the present invention may assume,

Figure 1 is a top plan view of the forward end portion of a motor vehicle showing the invention applied thereto.

Fig. 2 is a transverse section thereof on line 2-2 of Fig. 1, depicting the forward mounting,

Fig. 3 is a similar view on line 3-3 of Fig. 1 illustrating the rear mounting for the motor, and

Fig. 4 is a vertical section on line 4-4 of Fig. 2 further illustrating the forward mountin Referring more in detail to the accompanylng drawings, the numerals 1 designate the side frame members of the vehicle chassis, which are of the usual channel bar formation and between which the motor 2 is arranged.

A spanner frame or transverse frame member 3 has its ends flanged and bolted or secured in the opposing channels of the side frame member, as at 4. The spanner frame is bowed or depressed between its ends, as depicted in Fig. 2. and is formed in its upper edge with a central bearing or seat 5. A cap or strap bearin 6 is secured to the spanner frame over t 1e bearing 5 by bolts 7 which preferably pass vertically through said frame, the bearing 8 of the strap and bearing 5 being semi-circular and transversely concave to receive a partly spherical bushing 9. The trunnion 10 or engine shaft extension, a the case may be, finds support in this rockable bushing or journal bearing 9.

The rear support for the motor comprises two point of suspension, one on each side of the same. Bolted to the upper face of each side flange 11 of the engine base or crank case is a hanger or bracket 12 in the outer side face of which is threaded a trunnion 13 having a ball or globular end overhanging the adjacent frame member 1. A twopart socket bearing member H is bolted to the socketed bearings 11 are removed as well as cap bearing 6 whereupon the engine or motor may readily and easily be set in place with the trunnion supports engaged in their bearings or seats. The component sections of the three bearings are then bolted over the trunnions for securely holding them in their seats. The motor is thereby firmly supported in a most etlicient manner without the employment of a complicated han 1' requiring the removal of a large numfir of bolts and nuts.

The mounting is flexible to accommodate itself to the twisting or relative movement between the frame members of the chassis. In traveling over rough roads especially, the

. chassis frame is subjected to much strain and torque which often causes a weakening of the frame and a loosening of the engine mounting. A ain, the engine mounting be comes loosene through vibration of the motor. These severe conditions are effectively taken care of by this flexible mounting.

Furthermore, by removing cap bearing 6 the 11, pass on opposite sides of the trunnion mountings to steady and reinforce such mounting. All the parts are readily accessible through the removal of a small number of bolts.

Having thus described my invention, whatv I claim as new and desire to secure by Letters Patent is In combination with the sides of a chasformed to each seat at their lower ends on the flanged base of the motor, said brackets 15 having vertical lengthwise holes formed therethrough, trunnions carried by the brackets and arranged in said bearings, and bolts extending through the flange of the. motor base and through said holes of the bracket and having their heads engaged with the under face of the flanges of the motor base and having nuts seated on the top ends of the brackets.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
